1 Claim.

This invention is a device which may be termed a natural gas dispenser,being adapted especially for projecting natural gas together with asufiicient quantity of air into an internal combustion engine for usethereby as fuel.

An object of the invention is to provide a device of this characterwhich may be readily applied to an internal combustion engine andcontrolled from a dash control device or in any other suitable mannerfor supplying a mixture of natural gas and air into an internalcombustion engine.

The invention together with its objects and advantages will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawings, wherein:

Figure 1 is a side elevational view of the device.

Figure 2 is a top plan view thereof.

Figure 3 is a vertical sectional view therethrough and.

Figure 4 is a transverse sectional view taken substantially on the line4-4 of Figure 1. Referring to the drawings by reference numerals it willbe seen that the device is in the nature of a carbureter and includes acylinder 5 to the upper end of which is secured a collar 6 provided withan apertured flange 1 whereby it may be secured by suitable fasteningmeans to the neck of the intake manifold of an internal combustionengine for securing the device in position on the internal combustionengine. Adjacent the bottom thereof the body or cylinder 5 is providedwith a series of air ports 8 controlled by a sleeve valve 9. The sleevevalve 9 has apertured lugs I0 integral therewith and slidably engagingguide rods II that have ends extending through apertures provided inears I2 integral with the collar 6 and ears I3 integral with thecylinder 5 at the lower end of the cylinder. The upper ends of the rodsI I are provided with cotter pins I l while the lower ends of therodsare provided with nuts I5. The sleeve valve 9 is normally urgeddownwardly into a closing position with respect to the ports 8 throughthe medium of 'coil springs I6 disposed about the rods between the earsIll and I2.

In the bottom thereof the cylinder 5 is provided with an aperturethrough which there projects the tubular body I! of a fuel jet which issuitably coupled .at its lower end with an elbow I8 that in turn servesto connect the jet with a conduit or the like leading from a suitablesource of supply.

The upper or inner end of the body I! of the jet is tapered and isprovided with a substantially frusto-conical discharge orifice I9, andat the inner end of this orifice with a substantial frustoconical valveseat 20.

Arranged to engage the valve seat 20 is a substantially conical valve 2|provided with a stem 22 that is pivoted at its upper end to an arm 23. 5Arm 23 at one end is pivoted to a suitable bracket 24 mounted within thecylinder 5 adjacent the upper end of the latter. The valve M is normallyurged upwardly into engagement with the seat 20 through the medium of acoil spring 25 that 10 impinges against the valve 2| and has a bottomend resting on a suitable annular ledge 26 provided therefor internallyof the body I I of the jet.

For controlling the operation of the valve 2! there is provided acontrol rod 21, and this rod 15 at its upper end is pivoted to the freeend of the arm 23 as clearly suggested in Figure 3.

At its lower end the rod 27 extends through the bottom of the cylinder 5and is provided with a lateral projection operating in an arcuate slot28 provided in one end of a gas control lever 29.

The gas control lever 29 is pivoted intermediate its ends to a bracketplate 30 that has an apertured flange portion thereof clamped betweenone of the ears I3 and a nut I5 on the guide rod II extending throughsaid one ear I3.

Any suitable mechanism may be provided for controlling the operation ofthe device, and as shown such mechanism may consist of a lever dividedinto two parts and having end portions 30 SI pivoted as at 32 toopposite sides of the sleeve valve 9. Adjacent the ends 3| the parts ofthe lever are also pivoted as at 33 between upstanding links or posts 34pivoted at their lower ends as at 35 to a plate 36 clamped between asec- 35 ond one of the ears I3 and the nut I5 on the rod I I passingthrough the aperture in the second named ear I3 as suggested in Figure3. As shown in Figure 2 between one of the pivots 32 and the free end ofthe lever 29 there is a link 40 connection 31 and for connecting one endof the link 31 with the gas control lever 29 the latter lever isprovided with a series of openings 38 and bolt and nut means 39 carriedby the link 37 is engaged with a selected one of the apertures 45 38 toadjustably connect the link 31 and lever 29. The aforementioned leverincludes besides the end portions 3I shank portions 3Ia connected bybolts 40, and the shank portions cm are of dilferentlengths as clearlyshown in Figure 2. 50 The longer of the shanks 3Ia is provided with aflange having an aperture for rotatably receiving the head equipped endof a screw 4| which latter, at the end opposite to the head thereof isswivelly connected with a flange on one end of a plate 42 and is securedthrough the medium of the bolt 40 between parallel portions of theshanks 3|a. On the bolt 4| there is a nut 44 carrying an apertured lugfor engagement with one end of a Bowden wire or the like forming part ofa remote control device for the dispenser.

From the above description it will be apparent that in operation when itis desired to admit a quantity of natural gas and air into the internalcombustion engine the operator pulls on the remote control device torotate the lever 3Ia and thereby move the valve 9 to the open positionsuggested in Figure 3. This upward movement of valve 9 will cause a pullon the link 31 for rotating the lever 29 in a counterclockwise directionresulting in a downward pull on the valve control rod 21. This pull onthe rod will cause the arm 23 to move downwardly for unseatlng the valve2| against the action of spring 25 so that in fully open position theparts are as shown in Figure 3. With the parts in open position naturalgas from a source of supply will flow through the elbow IS the jet l1and the cylinder 5 into the intake manifold of the internal combustionengine. At the same time air from the atmosphere will be admittedthrough the ports 8 to mingle with the natural gas as it dischargesthrough the orifice l9, thus insuring a proper mixture 01 natural gasand air to obtain proper combustion.

Having thus described my invention, what I claim as new is:

A device of the class described comprising a cylinder having ports inone end portion thereof, a gas supply pipe entering said end of thecylinder and having a nozzle at its inner end extending into thecylinder to a point spaced inwardly from the ports, that portion of thepipe within the cylinder being concentrically arranged with relation tothe cylinder, the inner face of the nozzle having a valve seat therein,a valve located in the pipe, a spring for holding the valve against theseat, a stem connected with the valve and passing through the nozzleinto the cylinder, an arm pivoted to an internal part of the cylinderand pivoted to the stem, a rod connected with the arm and passingthrough the ported end of the cylinder, a lever pivoted to said end ofthe cylinder and connected with the rod, a sleeve valve slidablyarranged on the cylinder, spring means for normally holding the valve ina position covering the ports in the cylinder, a lever pivotallysupported intermediate its ends, means for connecting one end of thelever to the sleeve valve for moving the valve to open position when thelever is moved in one direction, and a link connecting the firstmentioned lever with the second lever whereby movement of the secondlever is communicated to the first lever to open both valvessimultaneously against the action of the springs.
